MCP Setup — AI Assistant Tools (Claude Desktop, Cursor)

ThetaPrime can expose read-only tools to an MCP-capable AI assistant, so you can ask things like "what's my BankNifty strangle's P&L right now" or "is today's reconciliation clean" without opening the dashboard.

This is local and read-only. The assistant spawns mcp_server.py on your own machine; it talks to your already-running ThetaPrime over localhost only — nothing is exposed to the internet, and no strategy can be armed, disarmed, or closed through it.

Requirements

• ThetaPrime must be running — the tools read from it live, they don't work standalone.

• A separate Python install to run mcp_server.py under, with the mcp and requests packages — ThetaPrime's own bundled runtime isn't a general-purpose interpreter and can't run other scripts. Any recent Python 3 from python.org works; this is unrelated to and doesn't affect your ThetaPrime install.

powershell pip install mcp requests

• Your dashboard password (Settings → the same one you log in with).

Configure Claude Desktop

mcp_server.py ships in your install directory alongside app.exe (default C:\Program Files\ThetaPrime\mcp_server.py — check your Start Menu shortcut's target if you installed elsewhere).

Edit claude_desktop_config.json at %APPDATA%\Claude\claude_desktop_config.json.

{
  "mcpServers": {
    "thetaprime": {
      "command": "C:\\Users\\you\\AppData\\Local\\Programs\\Python\\Python312\\python.exe",
      "args": ["C:\\Program Files\\ThetaPrime\\mcp_server.py"],

        "THETAPRIME_MCP_PASSWORD": "your-dashboard-password"
      }
    }
  }
}

Not sure which python.exe you have? Run (Get-Command python).Source in PowerShell (after installing Python, if you haven't already).

Restart Claude Desktop after saving.

Tools

Not included

No write tools — arming, disarming, or closing a position always goes through the dashboard. There's no raw order-placement tool either way; ThetaPrime's unit is a configured strategy, not a manual order.
